Solution

The correct option is D Erythromycin
Erythromycin is an antibiotic useful for the treatment of a number of bacterial infections. It is in the macrolide class and has an antimicrobial spectrum similar to or slightly wider than that of penicillin, and is often prescribed for people who have an allergy to penicillins. They bind to 50S ribosome and inhibit the protein synthesis of pathogens.
